From the leaves of Melicope triphylla MERR., three new flavonoids (1-3) were isolated, together with nine known flavonoids, 4', 5-dihydroxy-3,3', 7-trimethoxyflavone (4), 5-hydroxy-3,3', 4', 7-tetramethoxyflavone (5), 3,3', 4', 5,7-pentamethoxyflavone (6), 7-hydroxy-3,3', 4', 5,8-pentamethoxyflavone (7), 3,3', 4', 5,7,8-hexamethoxyflavone (8), 5-hydroxy-3,7,8-trimethoxy-3', 4'-methylenedioxyflavone (9), 7-hydroxy-3,5,8-trimethoxy-3', 4'-methylenedioxyflavone (10), 3,5,7,8-tetramethoxy-3', 4'-methylenedioxyflavone (11), and 5-hydroxy-3,6,7,8-tetramethoxy-3', 4'-methylenedioxyflavone (12). The structures of 1,2,and 3 were established as 5-hydroxy-3,7-dimethoxy-3', 4'-methylenedioxyflavone, 5-hydroxy-7-isopentenyloxy-3,8-dimethoxy-3', 4'-methylenedioxyflavone, and 4'-hydroxy-7-isopentenyloxy-3,3', 5,8-tetramethoxyflavone by their respective chemical and spectral data. The 20 flavonoids isolated from this plant were examined for the piscicidal activities.
